Mango plant

[Shahar]

Hi,
So I've had this mango growing from seed and it's been doing really well. Went away on holiday for a month, asking my landlord to water my plants occasionally, and when I came back it looks like in the picture.
Any advice on what's going wrong? Too much/little water? Should it move indoors for winter? etc.
It's growing up in North India, usually been kept outdoors on balcony.
Thanks

It looks to me as if it has had too much water, the soil is staying too wet and it has contracted a fungus. I don't know your climate but mangos like it to be at least 70F (21C) and live in slightly damp well drained soil.
